A tubing head is a wellhead component consisting of a body with two flanges, that support the tubing hanger, and provide a means of attaching the Christmas tree to the wellhead. It seals off the pressure between the casing and tubing annulus and connects with the tubing adapter on the top.
The tubing head is the topmost spool in a wellhead assembly and is responsible for supporting and sealing the tubing string. The upper section of the tubing head has a straight-shaped bowl and a 45-degree load shoulder that helps support and seal the tubing string through a tubing hanger.
A forged tubing head is used in oil and gas wellheads and is designed to perform several important functions:
